  Design Note 332

  Introduction
  The LTC®3425 is the industry’s first 4-phase, monolithic
  synchronous boost converter. It can start up with as little
  as 1V and operate with inputs up to 4.5V. The output
  voltage range is 2.4V to 5.25V, making it well suited
  for battery-powered applications as well as point-ofload regulation in low voltage systems. The 4-phase
  architecture allows for an effective switching frequency
  of up to 8MHz, which in turn reduces output ripple current and peak inductor current by a factor of four (over
  an equivalent single-phase circuit). This allows the use
  of small, low cost, low profile inductors and ceramic
  capacitors even at high load currents. With 5A peak current capability and an effective switch
  RDS(ON) of 40mО© (NMOS) and 50mО© (PMOS), the
  LTC3425 is capable of efficiently delivering 2.5A load
  current from a 0.8mm maximum profile, 32-pin 5mm
  Г— 5mm QFN package.
  Multiple Operating Modes Optimize Performance
  in Different Applications
  The LTC3425 can be configured for automatic Burst
  ModeВ® operation, п¬Ѓxed frequency mode with forced …
